He became governor himself when Warren resigned to become Chief Justice of the United States in 1953.

As governor, Knight fought for control of the Republican Party of California with U.S. Senate Majority LeaderWilliam Knowland and Vice President Richard Nixon. In 1954, Knight was easily elected to his own full term. At first Knight seemed to make an alliance with Knowland, but this began to sour in 1956 when Knowland supported Nixon for renomination as vice president. In 1957, Knowland announced that he would challenge Knight in the 1958 Republicanprimary for governor. Knight, known as a moderate, and sympathetic to organized labor, faced a serious threat from more conservative challengers. He was induced by Knowland, Nixon, President Dwight Eisenhower, and others to run for Knowland's Senate seat instead of running for governor again. Both Knowland and Knight went down in defeat in 1958, with Knowland losing the gubernatorial race to Edmund G. "Pat" Brown, Sr. and Knight losing the Senate race by over 10% to Clair Engle, severely weakening the heretofore-dominant Republicans in the state.
